Abstract
The piston liquid flow standard device volume calibration method of piston device volume model based on ideal cylindrical model is studied,the volume of the model is modified by introducing a correction factor,and quality method for calibration of the piston volume device using the law of conservation of mass is put forward.The correction coefficient is analyzed and the uncertainty is evaluated.The results show that the expanded uncertainty of 5L and above is 0.05％.The method is simple,controllable and accurate.关键词
